Legion Go + Razer Core X + 5070 Ti (also 3060/3080)

I've read a couple of times that TB3 severely bottlenecks GPUs and now I can confirm that :).

Got a 5070ti for my main desktop PC and finally got to try it out in a Razer Core X where my 3060 was living.

So with 5070ti I've got continuous stutter and inconsistent 10-30fps for games which get 60fps easily (my monitor is 60hz only, so limiting) on max settings on my main PC. Tried both 4k and 1440p in FF7 Rebirth Flying Saucer area with high, then medium settings and not much of a difference.

On a good side - GPU is mostly 30-40% loaded this way and temps are amazing :).

In brief, there is no point to go over 60 series in the TB3 docks, 3060 goes back into Razer, 5070ti to the main rig.

PS. Tried friend's 3080 in a Razer too, and it is doing the same thing as 5070ti with stutter and low fps.
